摘要:
Aspects of the present invention include interior vehicle trim panel having a sprayed expanded polyurethane layer and method of making same. In at least one embodiment, the method of making the vehicle interior trim panel comprises providing a skin layer on a spray tool, spraying expandable polyurethane reactive components onto the skin layer to form a resilient layer, and securing a rigid substrate on the resilient layer, such that the resilient layer extends between and connects the skin layer with the substrate to form the vehicle interior trim panel.

In at least one embodiment, the present invention takes the form of a panel comprising a substrate, a cover layer, and foam disposed between at least a portion of the substrate and the cover layer. At least one of the cover layer or the substrate being is provided with an integrally formed member for sealing the cover layer to the substrate. The present invention also relates to a method for forming the panel.

摘要:
A method of forming a polyurethane article wherein first and second components of a polyurethane system are sprayed into an unconfined space above a mold. The first and second components are sprayed together to mix initially in the space above the mold and then are deposited in the mold on an in-mold coating that was previously applied to the mold. The two components of the polyurethane system and in-mold coating are subsequently removed from the mold as a flexible polyurethane skin. The skin may then be placed in a second mold along with a reinforcement. Structural polyurethane foam may then be injected to the second mold where it bonds to the reinforcement and the skin to form a finished polyurethane article having a flexible skin adhered to its surface. A post-mix spray nozzle assembly is provided with a central nozzle forming a first hollow conical spray pattern and a coaxially aligned annular nozzle forming a second hollow conical spray pattern. The first and second hollow conical spray patterns intersect in space remote from the nozzle and form a hollow circular spray pattern.

A fluid delivery system is provided as a modular system. The fluid delivery system provides a fluid to a robotic spray applicator system that may be used to spray a mold with a motor release compound or in-mold coating. The fluid to be dispensed is contained in the drum and is provided through a fluid circuit including a peristaltic pump, a filter and a heater. The fluid is pumped through the fluid circuit to an applicator that dispenses the fluid onto a mold. The system may also be used in conjunction with adhesives or other compositions that must be filtered, heated and provided to a spray applicator at a metered flow rate. The fluid delivery system may be used in conjunction with a robotic system. The displacement of the peristaltic pump may be controlled by a variable frequency drive or may be controlled by a programmable logic controller of the robotic system.

An in-mold applicator and method for spraying a coating on difficult-to-reach surfaces of a mold is disclosed. The applicator includes a spray head and a base portion at an oblique angle to each other. The outer dimensions of the body portion and the spray head are sufficiently small so that taken in combination with the oblique angle, the applicator and method can enhance the spraying of the coating to difficult-to-reach surfaces within the mold.

The invention relates to an interior panel component and the method for making the component. The interior panel component for use with a vehicle includes a skin layer, and a resilient layer secured to the skin. The resilient layer is made from a polymeric MDI, a pure MDI, and a polyol. The polyol is less than 50 pphr of a soy-based polyol. The resilient layer is secured to a substrate to form the interior panel component.
摘要:
A method of cooling a PVC dry blend powder in a vessel by spraying a liquified inert gas into the vessel such that the liquified inert gas contacts the powder. The PVC dry blend powder is made by mixing a powdered PVC resin with ingredients selected from the group consisting of plasticizers, stabilizers, and pigments in a mixing vessel by using a heating and mixing cycle followed by a liquified inert gas cooling cycle. The flow properties of PVC dry blend powder made by this method have an improved shelf life.
